System for Restricting the Distribution of Attachments to Electronic Messages

1. A method of restricting the distribution of an image attachment to an electronic message sent by a sender to a recipient via an electronic communications network, the method comprising: receiving, via the electronic communications network, the electronic message at a server from the sender; removing, via the server, the image attachment from the electronic message; fragmenting, via the server, the image attachment into at least two different image parts; creating, via the server, a set of rendering instructions as to how the at least two different image parts should be displayed together to represent the image attachment; posting, by the server, the at least two different image parts to a web server; and forwarding the electronic message and the set of rendering instructions to the recipient, wherein the set of rendering instructions allows the recipient to reconstitute the image attachment by displaying the at least two different image parts together via the web server.

2. The method of claim 1 , wherein said set of rendering instructions comprises at least one link to a URL for each image part, wherein access to the at least one link to the URL by a web browser of the recipient allows the recipient to reconstitute the image.

3. The method of claim 1 , wherein the posting of the at least two different image parts to the web server expires after a predetermined amount of time or after the image has been reconstituted a predetermined number of times.

4. The method of claim 1 , further comprising transmitting the electronic message, the set of rendering instructions and the at least two different image parts to an application on a client machine of the recipient.

5. The method of claim 1 , wherein the electronic message is a text message, and the electronic communications network is a cellular network.

6. The method of claim 1 , wherein the electronic message is an electronic mail message, and the electronic communications network is the Internet.

7. The method of claim 1 , wherein the steps of removing, fragmenting and creating are performed only if distribution of the image attachment to the electronic message has been designated as being restricted.

8. A method of restricting the distribution of an image file attached to a text file sent by a sender to a recipient via a cellular network, the method comprising: receiving, via the cellular network, the text file with at least one reference to the image file at a server from the sender; fragmenting, via the server, the image file into at least two different image parts; replacing, via the server, the at least one reference to the image file in the text file with at least two new references to the at least two different image parts; posting, by the server, the at least two different image parts to a web server; and forwarding the text file and the set of rendering instructions to the recipient, wherein the set of rendering instructions allows the recipient to reconstitute the image file by displaying the at least two different image parts together via the web server.

9. The method of claim 8 , further comprising transmitting the text file with the at least two new references to the at least two different image parts to a client machine of the recipient.

10. The method of claim 9 , wherein the recipient's client machine, using an application, renders the resultant text file and reconstitutes the image from the at least two different image parts.

11. The method of claim 10 , wherein the application is a web browser that is used to render HTML markup, and the at least two different image parts are standard image files that are supported by a standard web browser.

12. The method of claim 8 , wherein access to at least two new references to the at least two different image parts expires after a predetermined amount of time or after the image file has been reconstituted a predetermined number of times.

13. The method of claim 8 , wherein the steps of fragmenting and replacing are performed only if distribution of the image file has been designated as being restricted.
